Study on three phase foam for Enhanced Oil Recovery in extra-low permeability reservoirs

Oil & Gas Science and Technology, 2018
Poly (MSt-MMA) nanosphere as foam stabilizing agent was synthesized by emulsion polymerization. The three phase foam was prepared with Disodium 4-Dodecyl-2,4′-Oxydiben Zenesulfonate (DOZS) as foaming agent, Hydrolyzed Polyacrylamide (HPAM) and ...
